Claims
What is claimed is:
1. A flushing system for a lavatory which comprises a lavatory bowl with a
lavatory seat disposed thereon, said flushing system comprising:
a first cistern which is a flexible and annular member for receiving water
therein, said first cistern being disposed between said lavatory seat and
said lavatory bowl such that when the weight of a user is applied to said
flexible and annular member water therein is forced to valve a means;
a block member attached to and being in fluid communication with said first
cistern, said block member having an exit defined laterally therein and a
tube extending therefrom;
said valve means being rotatably connected to said first cistern and having
an L-shaped path defined therein which comprises a first section and a
second section, said first section of said L-shaped path communicating
with said first cistern and said second section of said L-shaped path
adjustably and selectively alternatively communicating with said tube and
said exit by operating said valve means by a crank extending from said
valve means, and
a second cistern disposed above and in communication with said first
cistern.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a flushing system and more particularly,
to an improved flushing system having an annular and flexible first
cistern disposed between the lavatory seat and the lavatory bowl.
2. Brief Description of the Prior Art
Generally, a lavatory comprises a lavatory bowl and a flushing system which
is connected to and disposed above the lavatory bowl with a valve means
disposed therebetween such that the valve is operated to allow water in a
cistern of the flushing system to flush into the lavatory bowl. However,
in order to set the cistern above the lavatory bowl, the lavatory has to
be disposed away from a wall with a distance defined between the wall and
the lavatory and is connected to a pipe in the wall by a exhaust pipe
connected between the wall and the lavatory bowl such that the cistern
having a width the same as the distance between the wall and the lavatory
bowl is disposed above the lavatory bowl. This makes the lavatory occupies
a large amount of space. Furthermore, the cistern generally has about 10
liters of water therein so that there will be 10 liters of water flushed
into the lavatory bowl in one flush. This is deemed to waste too much
water during one flush. Another necessary equipment is a bidet, especially
in France, which provides a convenient way to clean bottom of a person
after he/she has used the lavatory. The bidet is generally disposed
separately from the lavatory bowl.
The present invention intends to provide an improved flushing system which
is disposed to the lavatory bowl and includes an annular and flexible
first cistern disposed between the lavatory bowl and the lavatory seat, a
tube connected to the annular cistern and a second cistern connected to
the annular cistern by a valve means so as to mitigate and/or obviate the
above-mentioned problems.
SUMMARY OF THE INVENTION
In one aspect of the present invention, there is provided a flushing system
for a lavatory which comprises a lavatory bowl with a lavatory seat
disposed thereto, the flushing system comprising a first cistern which is
a flexible and annular member and is disposed between the lavatory seat
and the lavatory bowl.
A block member is disposed in communication with the first cistern and has
an exit defined laterally therein and a tube extending therefrom. A valve
means is rotatably connected to the first cistern and has an L-shaped path
including a first section and a second section defined therein such that
the valve means is rotated by operating a crank extending from the valve
means. The first section of the L-shaped path communicates with the first
cistern and the second section of the L-shaped path adjustably
communicates with the tube and the exit by rotating the valve means.
A second cistern is disposed above and in communication with the first
cistern.
It is an object of the present invention to provide a flushing system
comprising a tube so as to clean the bottom of a user and an exit so as to
flush the lavatory bowl by operating a valve means.
It is another object of the present invention to provide a flushing system
wherein water in the first cistern is pressed to eject from the tube by a
weight of the user sat on a lavatory seat of the lavatory.
Other objects, advantages, and novel features of the invention will become
more apparent from the following detailed description when taken in
conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings and initially to FIGS. 1 through 3, a lavatory
comprises a lavatory bowl 10 with a lavatory seat 21 pivotally disposed
thereon, the lavatory bowl 10 having two threaded holes 122 defined in a
rear end thereof. Two supports 25 each have a threaded portion 252
extending therefrom so as to be threadedly engaged with the corresponding
threaded hole 122 of the lavatory bowl 10. Each of the supports 25 has a
recess 251 defined laterally therein and a cap 253 disposed on a top of
each of the supports 25. The flushing system in accordance with the
present invention generally includes a first cistern 22 which is a
flexible and an annular member and is disposed between the lavatory seat
21 and an upper portion of the lavatory bowl 10.
A block member 27 is disposed in communication with the first cistern 22
and has an exit 271 defined laterally therein and a tube 28 extending
therefrom. The tube 28 extends upwardly inclined manner from the block
member 27 and the exit 271 extends in a downwardly and inclined manner
from the block member 27.
Further referring to FIGS. 4 and 5, a valve means 26 is rotatably connected
to the first cistern 22 and has an L-shaped path 260 defined therein which
comprises a first section 263 and a second section 264. The first section
263 of the L-shaped path 260 communicates with the first cistern 22 and
the second section 264 of the L-shaped path 260 is adjustably and
selectably communicated with a first pipe 265 which communicates with the
tube 28 and a second pipe 266 which communicates with the exit 271 and by
rotating the valve means 26. FIG. 3 shows the second section 264 is
located at a close position where water neither flows from the tube 28 nor
the exit 271. A crank 261 extends from the valve means 26 such that the
valve means 26 is rotated by a user (not shown) by operating the crank
261.
A second cistern 23 is disposed above and in communication with the first
cistern 22 on the rear end of the lavatory bowl 10 and a lavatory lid 29
is pivotally disposed to the second cistern 23. The second cistern 23
communicates with a main pipe so as to supply water into the second
cistern 23.
When the crank 261 is rotated to rotate the valve means 26 to let the
second section 264 of the L-shaped path 260 communicate with the first
pipe 265 as shown in FIG. 4, water in the first cistern 22 is pressed by a
weight of a user sitting on the lavatory seat 21 to eject from the tube 28
via the first pipe 265 so as to clean the bottom of the user. When the
crank 261 is rotated to rotate the valve means 26 to let the first section
263 of the L-shaped path 260 communicate with the second pipe 266 as shown
in FIG. 5, water in the first cistern 22 is pressed by a weight of a user
(see FIG. 7) sitting on the lavatory seat 21 and to eject from the exit
271 via the second pipe 266 (see FIG. 6) so as to flush the lavatory bowl
10 wherein water in the second cistern 23 is supplied into the first
cistern 22 continuously.
The second cistern 23 has two axles 231, 232 respectively extending
laterally from two sides thereof so as to be inserted into the recess 251
of the corresponding support 25 with a spring 233 mounted on each of the
axles 231, 232. The spring 233 has one end 234 disposed against the
lavatory bowl 10 and the other end 235 disposed against a bottom of the
first cistern 22 such that when the user stands up, the first cistern 22
and the lavatory seat 21 are pivoted upwardly.
Accordingly, the present invention provides a flushing system utilize the
user's weight to press water in the first cistern 22 to eject from the
tube 28 or the exit 271 by operating the valve means 26.
Although the invention has been explained in relation to its preferred
embodiment, it is to be understood that many other possible modifications
and variations can be made without departing from the spirit and scope of
the invention as hereinafter claimed.
